Why variables store data in PowerShell - See It in Action

Why variables store data

📖 Scenario: You are learning how to use variables in PowerShell to store information. Variables help you keep data so you can use it later in your script, just like putting things in labeled boxes to find them easily.

🎯 Goal: Build a simple PowerShell script that creates a variable to store a name, then stores an age in another variable, and finally prints both values to the screen.

📋 What You'll Learn

Create a variable called $name and assign it the value "Alice"

Create a variable called $age and assign it the value 30

Print the values of $name and $age using Write-Output

💡 Why This Matters

🌍 Real World

Variables let you save user input, settings, or results in scripts to automate tasks.

💼 Career

Knowing how to store and use data in variables is a basic skill for any scripting or automation job.

1

Create a variable to store a name

Create a variable called $name and assign it the text value "Alice".

PowerShell

# Create a variable called $name and assign it "Alice"
# Your code here

Need a hint?

Use = to assign the value "Alice" to the variable $name.

2

Create a variable to store an age

Create a variable called $age and assign it the number 30.

PowerShell

$name = "Alice"
# Create a variable called $age and assign it 30
# Your code here

Need a hint?

Remember, numbers do not need quotes in PowerShell.

3

Print the stored name and age

Use Write-Output to print the values of $name and $age on separate lines.

PowerShell

$name = "Alice"
$age = 30
# Print $name and $age using Write-Output
# Your code here

Need a hint?

Use Write-Output followed by the variable name to display its value.

4

Run the script to see the output

Run the script to display the stored name and age. The output should show Alice on the first line and 30 on the second line.

PowerShell

$name = "Alice"
$age = 30
Write-Output $name
Write-Output $age
# Run the script to see the output

Need a hint?

Run the script by pressing Enter or using your PowerShell environment's run command.
